FLEXIBLE SHUTTER on CURTAIN.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed June 1,' 1908. Serial No. 436,022.

To all whom it may concern:

Be it known that I, ALBERT RUSH, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented a certain new and useful Improvement in Flexible Shuttersor- Curtains, of which the following is a specitication.

The principal object of this invention is to provide a flexible shutteror curtain composed of jointed slats or sections in which either, sidecan be used as the ex osed or weather side, and so that either side,when the shutter or curtain is properly shall shed water effectually.

The invention consists in the construction hereinafter described andparticularly pointhung,

In the accompanying drawings in which one embodiment of the invention isilluslratedl*igure 1 is a combined vertical section and isometricperspective of a portion of a curtain or shutter acc'ording to theinvention; Fig. 2 is a vertical section showing a shutter hung with asmooth side as the weather side; Fig. 3 is a similar section showing theshutter inverted and hung with the joint containing side as the weatherside.

The slats or sections are preferably made of strips of sheet metalwith'their lon itudinal edges bent as shown to form tie jointingmembers. 4: designates the body of the slat. The opposite edges of thestrip are bent to form shoulders 5 and 6 in parallel planes inclined tothe general plane of the body ofthe slat. These shoulders are extendedrespectively toward the acute an le made by the shoulder with the planeof t e slat in the form of rolls, as seen respectively at 5 and 6, theroll 5 being of larger di-. ameter than the roll 6, so that the lattercan he slid longitudinally into the former to eifect an interlockingconnection and prevent their lateral separation when the shutter is jflexed as in rolling it up on a roller. It will be noted that the rolls5 and 6 are formed by bending the metal tothe side toward which theshoulders are inclined. From I this construction it will be observedthat ample flexibility of the shutter is provided for; and also that thethrust of the slats to gether is borne by the inclined shoulders andespecially when the edges of the shutter are confined in guidingchannels, as is usual in the class of shutters to which this inventionbelongs. It will also be observed that by inversion either side isadapted to effectually shed water and can be used as the weather side,as illustrated in Figs. 2 and 3. Endlocks, as seen at 7, to preventlongitudinal movement of the slats on each other can be secured byrivets or otherwise to the ends of alternate slats.

\Vhat I claim and desire to secure by Letters Patent is: i

1. A flexible shutter or curtain constructed chiefly of slate orsections having their opposite edges formed with shoulders parallellyinclined to the general plane of the slats, and with interlockingextensions of said shoulders bent respectively toward the acute andobtuse angles formed by the shoulders with the plane of the slat.

2. A flexible shutter or curtain constructed chiefly of slats orsections having their opposite edges formed with shoulders parallellyinclined to the general plane of the slats, said shoulders beingextended and bent respectively toward the acute and obtuse angles formedby the shoulders with the plane of the slats to form interlockingrolls,-

substantially as described.

3. slat for the construction of flexible shutters or curtains consistingof a strip of sheet metal having its opposite edges bent to formparallel shoulders inclined to the gen.- eral plane of the slat, saidshoulders being extended and bent respectively toward the acute andobtuse angles formed by the shoulders with the plane of the slat to formrolls adapted to interlock with rolls of similarly formed slats.
